Brake Rotors vs the 50cal...

Duration: 12:31

This video from Demolition Ranch features Matt Carriker conducting an experiment to test the penetration capabilities of various firearm calibers against stacked automotive brake rotors. The test includes calibers ranging from .22 LR to .50 BMG, fired from different platforms like an AR-15 and a Barrett M107A1. The results demonstrate that while smaller calibers are largely ineffective, larger rifle rounds can penetrate multiple rotors, and brake rotors can serve as surprisingly effective improvised armor against certain small arms.

Quick Summary

Demolition Ranch tested brake rotors against calibers from .22 LR to .50 BMG. Results showed smaller calibers were ineffective, while .338 Lapua Magnum and .50 BMG rounds achieved significant penetration, demonstrating brake rotors' potential as improvised armor against certain firearms.

Frequently Asked Questions

What calibers were tested against brake rotors on Demolition Ranch?

The video tested a range of calibers including .22 LR, .45 ACP, .22 Hornet, .44 Magnum, 5.56x45mm, .338 Lapua Magnum, and .50 BMG, fired from various firearms like a Ruger Mark I, AR-15, and a Barrett M107A1.

How effective are brake rotors as improvised armor?

The experiment showed that brake rotors can act as effective improvised armor against smaller caliber rounds like .22 LR and .45 ACP. However, larger rifle calibers such as .338 Lapua Magnum and .50 BMG demonstrated significant penetration capabilities.

Which firearm showed the most penetration power against brake rotors?

The Barrett M107A1 chambered in .50 BMG exhibited the greatest penetration power, successfully piercing multiple stacked brake rotors, including with specialized APIT ammunition.

What was the purpose of applying brake cleaner and starter fluid?

Brake cleaner was applied to observe if high-velocity impacts could cause ignition. Starter fluid was used in a final test to create a visible fire effect after the projectile impacts.
